钛合金表面涂层应用于生物骨的研究

The Research of Titanium Alloy Applied to the Bioactive Bone Surface Treatments

目的探讨人工材料自身在生物体内具有与生物体活性陶瓷相同的生物相容性。方法用化学方法赋予Ti及Ti合金与生物骨的结合性能,采用NaOH水溶液处理后,在Ti及Ti合金表面上形成的Na2O-TiO2成份是从外到里逐渐减少的这种梯度结构层;采用X射线光电子能谱仪及扫描电子显微镜观察了其表面结构的变化。结果利用动物试验研究了Ti及Ti合金与生物骨的结合性能。结论 本方法赋予的Ti及其合金的生物活性层,其强度、韧性及与生物骨的结合性能均很优异,可望能作为承受大载荷状态生物骨的修复材料。

Objective Probe into artificial material oneself in the organism having the same organism compatible performance as active pottery of material living beings. Methods It gives Ti and Ti alloy and living beings the combination performances of bone with chemical methods. After adopting NaOH water solution treating, composition of Na2O-TiO2 formed on the surface of Ti and Ti alloy is the kind of gradient structure layer reducing gradually from outside to inside; adopt X ray photoelectron energy spectrum and scanning electron microscope watch their changes of the structure. Results Utilize animal experimental to study combination performance of Ti and Ti alloy in the living beings bone. Conclusion This way gives Ti and Ti alloy the living beings activation layer. Its intensity, toughness and performance of combination with living beings are excellent. Being expected to be as bearing repairing material for great loaded state living beings bone.
